Host of KPFA-FM's Ode to Gravity series Charles Amirkhanian, interviewed French composer Luc Ferrari at his home in Paris in June of 1972. The night before the interview, Ferrari had a world premiere performance of his "Monologos I" at the Opera Comique. Ferrari discusses his compositional practices and experiments in voice and tape delay that developed into Monologos I. The two also talk about Ferrari's activities since 1970 which included the writing of his book "Les réalisable et le journal d'un autobiographe", a work of text compositions and part autobiography; and creating the first sonic chapter of his "ecological" series in observation, "Allô ici la terre". The interview also takes a philosophical turn as Ferrari describes the non-existence of "truth" or any correct "system", political or otherwise, and how we must devise many different ways of going about the act of living.
